Sorry for the late reply, after consulting with our Horticulture Agent in Harris County it looks like your fig has a fungus known as fig rust. Healthy fig leaves are usually a bright green color, but you may start noticing yellow spots. Eventually, these spots get bigger, and they turn to a brownish color. You may also notice raised brown spots or lesions on the underside of the leaves. Over time, the leaves will be completely yellow, and then they’ll turn brown before falling off of the tree. Although there’s no surefire way to prevent fig rust, it’s easier to take preventative measures than fight a full-blown fungal infection. Good management practices like proper pruning, cleaning up leaf litter and not overwatering are a couple good techniques to acquire if you have not already. Any lime or copper sulfate Fungicides should be applied in the spring when the first leaves are completely grown and make additional applications as new growth is formed. Do not spray when the fruit is one-fourth inch in diameter as the spray residue will make the fruit unattractive. Resume spraying after the fruit has been harvested.
Fortunately, this disease doesn’t cause immediate long-term damage to your tree, so you shouldn’t lose hope when you notice the yellow or brown spots on your fig tree’s leaves. Attached are some helpful articles on the disease on how to manage/treat for Fig rust.
